When an atom of sodium and an atom of fluorine combine to form the salt, sodium fluoride, anionic bond, is formed. Which statement correctly describes the behavior of the valence electron in the ionic bond? 5 points
An electron from the fluorine atom moves to the sodium atom
An electron from the sodium atom moves to the fluorine atom
The fluorine atom shares an electron with the sodium atom filling their outer shells
The sodium atom shares an electron with the fluorine atom filling its outer shells

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

the correct answer is:

a. formation of precipitation

answerto predict;

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
